Are lithium ion batteries better than NMC batteries?

Lithium-ion batteries that use iron and phosphorous in their cathodes, known as LFP batteries, are an alternative to NMC batteries. However, their higher weight per unit of energy (i.e., lower energy density) results in less EV range.

Are lithium-ion batteries Green?

Lithium-ion batteries were supposed to be different from the dirty, toxic technologies of the past. Lighter and packing more energy than conventional lead-acid batteries, these cobalt-rich batteries are seen as “green.” They are essential to plans for one day moving beyond smog-belching gasoline engines.

Will lithium ion batteries be affordable by 2020?

Panasonic, Samsung SDI and LG Chem lithium ion batteries were further expected to be affordable by 2020 [ 1 ]. The implications of this study are of primary importance for sustainable mobility consumers, i.e., the global population who will use renewable energy for mobility.

Should artisanal mining be a boon for Congo?

Artisanal miners alone are responsible for more cobalt than any nation other than Congo, ranking behind only Congo’s industrial mines. The industry should be a boon for a country that the United Nations ranks among the least developed. But it hasn’t worked out that way.

Do cobalt miners in Congo use hand tools?

An estimated 100,000 cobalt miners in Congo use hand tools to dig hundreds of feet underground with little oversight and few safety measures, according to workers, government officials and evidence found by The Washington Post during visits to remote mines. Deaths and injuries are common.
